spark运行写入doris的任务报错park.DorisStreamLoad: Doris BE’s response cannot map to schema

在CDH的集群上跑spark任务，运行报错：
ERROR spark.DorisStreamLoad: Doris BE’s response cannot map to schema. res: “Access denied for user ‘default_cluster:hdfs@10.0.10.101’ (using password: YES)”
org.apache.doris.shaded.com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot construct instance of org.apache.doris.spark.rest.models.BackendV2 (although at least one Creator exists): no String-argument constructor/factory method to deserialize from String value (‘Access denied for user ‘default_cluster:hdfs@10.0.10.101′ (using password: YES)’)
at [Source: (String)””Access denied for user ‘default_cluster:hdfs@10.0.10.101’

查了一下，连接doris的用户名和密码没错。后来发现，spark-submit的参数–conf spark.user=hdfs 影响了，把这个参数去掉就正常了。
